JOHN A. DE VILBIS-S, OF ST. LOUIS, MISSOURI, ASSIGNOR 130' JOHN V. LEE, OF ST. LOUIS MISSOURI.

SAFE.

Application filed May 16, 1924. Serial No. 713,657.

To all whom it may concern Be it known that I, JoHN A. DE VILBIss, a citizen of the United States of America, a resident of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Safes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to improvements in safes, and the main object of the invention is to produce a safe which is so constructed as to withstand the attempts of persons to gain access to the interior thereof by blowing the door from said safe by means of an explosive charge.

Briefly stated, my improved safe comprises an outer compartment, a second compartment located within said outer compartment, and a door hinged to said second compartment and adapted to be locked within a doorway formed in a wall of said outer compartment, the contacting faces of said door and doorway being plane instead of stepped as heretofore, thereby eliminating all abutment faces between which a charge of explosive may be exploded to blow the door from the safe.

With the foregoing and-other objects in view, the invention comprises the novel con struction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the referred embodiment of the invention. owever, it is to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

Fig. I is a horizontal section of a safe made in accordance with my invention.

Fig. II is a cross section on line II-II of Fig. I.

Fig, III is a plan view on a reduced scale of my improved safe showing same as it would appear when the inner compartment has been moved outwardly to permit the outer door to be swung to an open position. a

In the drawing, A designates my improved safe which comprises an outer compartment B and an inner compartment C. The outer compartment or receptacle B is in the form of a safe having a top wall 1, a bottom wall 2, side walls 3 and 4, a rear wall 5 and a front wall 6. 7 designates a comparatively thick door which is adapted to lie within a doorway 8 in the front wall of the outer compartment B. The outer compartment B is provided with a plurality of rectangular ribs 9 which extend inwardly from the side, top and bottom walls of said outer compartment, said rectangular ribs being preferably formed integral with said side, top and bottom wall of said outer compartment.

Arranged within the outer compartment B is an elongated shell 10, which as is clearly shown in Fig. II is rectangular in crosssection. The side, top and bottom walls of said rectangular shell 10 contact with the inside faces of the rectangular ribs 9 so that said shell 10 is supported by said ribs. The shell 10, as will be observed by referring to Fig. I, is open at its opposite ends.

Located within the elongated shell 10 is the inner compartment C. The compartment C has the same cross sectional shape as the elongated shell 10 and as the outer compartment B. In other words, said inner compartment has an upper, a lower and side walls which are in close contact with the upper, lower and side walls of the elongated shell 10 (Fig. II), and while the walls of said inner compartment are in contact with the walls of said elongated shell, the relative cross sectional dimensions of said parts are such that said inner compartment may be moved longitudinally of said elongated shell. As clearly shown in Fig. I, the comparatively thick door 7 which has been described as being adapted to be moved into the doorway 8 is supported by the inner compartment C, there being hinges 11 whereby said door may swing relative to said inner compartment. Arranged within the inner compartment C is a second door 12, which is hingedly supported by a wall of said inner compartment at a point which is adjacent to the forward end of said inner compartment. The door 12 is of the ordinary type and is provided with any suitable locking mechanism.

The door 7 fits closely within the doorway 8, and said door has plane top and bottom edges and plane side edges. The

doorway 8 is likewise provided with plane door-receiving surfaces surrounding and conforming to said door edges when the door is in a closed position, and as a result of this the thick door 7 cannot swing in an arc of a circle whil it is confined in the doorway, but must be moved in a straight line parallel with the plane surfaces. The door 7, as has already been stated, is hingedly supported by the slidable inner compartment C.

13 designates locking bolts of a well known type which are carried by the door 7 and are adapted to project from the plane edges thereof as shown by dotted lines in Fig. I, so as to enter the recesses in the plane faces of a doorway 8. lt designates an operating handle adapted to control the locking bolts through the medium of mechanism not shown, and 15 designates the rotary dial of a combination look. It is understood, however, that other suitable looking means could be used in connection with the door herein shown.

When the door 7 is closed an explosive charge may be forced between the plane edges of said door and the plane surfaces of the doorway, but when the char e is exploded be tween these plane faces its explosive force will not tend to destroy the locking bolts 18. Furthermore, the explosion between these plane surfaces of the door and doorway will not tend to force the door outwardly from the doorway as it would if said charge were exploded between abutting faces such as the abutting faces found when the ordinary stepped-edge safe-door is locked in a doorway prorided with corresponding steps.

To open the door after it has been unlocked the operating handle is grasped to pull the door 7 and the inner compartment C associated therewith outwardly in a straight line, thereby locating the door and its hinges 11 in the positions in which they are shown in full lines in III. To completely open the door 7 the same operating member 14: is used to swing the door on its hinges to the position shown in dotted lines in Fig. HI. When the door 7 is closed the hinges ll lie within the safe, but after the door has been pulled to the position shown by full lines in Fig. III the hinges 11 are outside of the safe and at the corner of the doorway.

Arranged between the rear wall of the outer compartment B and the rear wall of the inner compartment C is a pair of coil springs 16. The coil springs 16 are of such length that when the inner compartment is in its rearmost position and the door 7 locked in the doorway 8, said springs are under compression, consequently when the locking bolts 13 are withdrawn from the recesses in the walls of the door opening 8 said coil springs will exert a forward pressure against the inner compartment C,

thereby rendering it possible to draw said 'nner compartment C out ardly from the outer compartment with very little effort.

To increase the ability of my improved safe to withstand the and heat, I provide the outer compartment thereof with a lin ing of a suitable insulating material, as in dicated by the reference character 17 in 1n manufzmturing my improved safe I prefer that the outer compartment l3 and the door 7 he formed of a very hard material, such as manganese steel, but because they are located within said outer compartment and are thus protected th reby it will not be nect sary to form the inner compartnient C or the rectangular shell 10 of as ha (i a material as the outer compartment, but on the other hand, they may be formed of a less expensive material whereby the cost of producing the safe is reduced.
